There may be some advantage to using free T4 (MED) over total T4 in discriminating between ESS and hypothyroidism, because free T4 is influenced less by ESS.

Many patients with primary hypothyroidism have normal circulating levels of triiodothyronine (T3), probably caused by sustained TSH stimulation of the failing thyroid, resulting in preferential synthesis and secretion of biologically active T3. WebbThyroxine (T4) is the main thyroid hormone secreted into the bloodstream by the thyroid gland.
